Fall back to AWS CloudFront
There is a backup Content Delivery Network (CDN) that can be used if Fastly is down. This backup CDN is currently provided by AWS CloudFront.
Important At the time of writing, GOV.UK will be served by static mirrors and not the origin of GOV.UK if you fallback to the backup CDN.
You will have to make 2 DNS changes to GOV.UK:
you will have to ask JISC (very few people are authorised to make such changes) to change the cname of
wwwAWS CloudFront distribution domain. You can log into the AWS web console to find the
wwwAWS CloudFront distribution domain.
you will have to change the cname of
assets.publishing.service.gov.ukto the the
assetsAWS CloudFront distribution domain using the usual gov.uk processes. You can log into the AWS web console to find the
assetsAWS CloudFront distribution domain.
